Re: Salt vs copper sulfate for caps

Hmm, that's odd: 500 grams is  about 1 pound.  So that might actually be more
expensive than the price I quoted for 2 pounds.  But that raises another 
question:
why did 1 pound of copper sulfate make a saturated solution for 3 gallons 
of water
for you, when it should take 2 pounds/gallon according to the MSDS?

What form of copper sulfate was the stuff you bought--was it copper sulfate
pentahydrate (which is what I was talking about), or might it have been 
something
else?  Any other suggestions?
